Comparison of HPCC and JNAC - I

Comparison of HPCC and JNAC - I

• Both set a hardware goal (teraflop for HPCC and petaflop for JNAC) to focus activity but in each case systems and applications were main justification
• Both couple applications with software and architectures in multidisciplinary teams with multi-agency support
• HPCC was dominantly research
  • JNAC is roughly 50-50 research and development
• HPCC inevitably developed MPP’s and transferred parallel computing to computing mainstream
  • JNAC’s challenge is memory hierarchy and will transfer understanding of this to mainstream independent of parallelism
